**FH Guangdong Fenghua Advanced Tech** · NTC Thermistors · 1206

CMFC104J4150HANT from FH Guangdong Fenghua Advanced Tech, in a 1206. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One of two terminal electrodes (Ag with Ni/Sn plating) of the chip NTC thermistor, 100 kΩ R25 ±5%, B25/50 4150 K, operating range -40℃ to +125℃; the part is non-polarized. |
| 2 | 2 | passive | The other terminal electrode (Ag with Ni/Sn plating) of the chip NTC thermistor, interchangeable with the first; 1206 body is 3.2×1.6 mm with 0.50 mm terminal length. |
